SINK-TRAP.

Specification of Letters Patent.

i Patented Nov. 12, 1918..

Application filed February 21, 1918. Serial No. 218,477.

To all whom it may concern: e

Be it known that I. OCTAVE J. Sr. PIERRE,

a subject of the King of Great Britain, re-

siding at Chauvin, in the Province of Alberta and Dominion of Canada,have invented new and useful Improvements in Sink-Traps, of which thefollowing is a specification.

This invention relates to traps for use in connection with kitchen sinksand the like, the object of the invention being to provide a trap to fitwithin the drain or wastepipe beneath the sink and which is adapted tocatch and retain all dirt, solid refuse andgrease and prevent the samefrom'passing into and clogging the pipe.

A further object of the invention is to provide a trap which willexclude all gases or odors, and which may be quickly and convenientlycleaned when required.

The invention consists of the features of construction. combination andarrangement of parts, hereinafter fully described and claimed, referencebeing bad to the accompanving drawing. in which Figure 1 is a frontelevation of the trap as applied for use.

Fig. 2 is a vertical front-to-rear section through the same.

Fig. 3 is a horizontal transverse section.

Fig. i is a view of the door and latch mechanism.

Fig. 5 is a detail section showing particularly the sealing means.

"in carrying my invention into pract ce I rovide a trap comprising acasino; 1 havmg a curved rear wall 2 andtiat parallel side walls 3.forming a casing devoid of interior angles and thus adapted to bereadily and Convenientlv brushed or otherwise cleansed. The casing isopen at the front and adapted to be closed bv a type of cover.hereinafter de cribed. and said casing is provided at its upper end withan inlet 4 and terminates at its lower end in a conical dischargeportion 5 leading to an outlet 6.

In practice the inlet 4 and outlet 6 are suitably coupled to portions 7and 8.0f the drain pipe leading from the outlet of the sink, whereby allthe waste water and refuse discharging from the sink will be caused topass into the trap before final discharge.

A removable door 9 is provided for closing the open front of the casing1, and this door is adapted to fit within the front of the casing and isformed with a marginal flange 10 to snugly embrace the outer faces ofthe wall 3 when the cover is in closed position. Adjacent to the flange10 the cover 9 is also provided with a marginal groove or recess 11 toreceive a packing or sealing gasket 12. of rubber or other suitablematerial, whereby when the door is closed an air. gas and liquid tightconnection will be furnished to prevent the escape of gases or odorsfrom the trap. as well as the leakage of any of its liquid contents.

The door is detachably fastened in closed position by locking meanscomprising a pair of oppositely movable locking rods 13. said rods beingsubstantially in axial alinement with each other. one of the rodsprojecting; upwardly and the other downwardly. The outer ends of therods terminate in tapered locking ends 14 for engagement with conical ortapered keeper recesses or sockets 15 formed at the too and bottom ofthe casing, whereby when the ends 14 of the rods are projected the doorwill be securelv locked in closed position. The tapered ends 14 of thelocking rods are adapted when eng ged with the tapered sockets to exerta wed ing action whereby an inward pressure will be exerted on the doorto crowd the gasket 12 against the edoes of the walls 3. thus sealingall spaces between the casing and door against any possibility ofleakage. The inner ends of the rods 13 have otlset nortions 16 arrangedto lie in parallel relation and spaced from each o her to receive anintermediate pinion 17. th said oflset portions 16 being provided withgear teeth 18 and forming racks for enoaaement with the pinion, wherebywhen the pinion is turned in one direction the rods or bolts will beprojected and when the pinion is turned in the opposite direction therods or bolts will be retracted. The mechanism for operating the rods isinclosed within a casing 19. and the gear-pinion 17 is mounted upon ashaft 20 provided with an operating handle 21, wherebythe lockingmechanism may be conveniently manipulated from the outside so as topermit the door to be unlocked and (ill: I

opened when it is desired to secure access to the trap and also toenable the door to refuse or particles of matter, but will per-' mit thewater to discharge for outlet from the trap, thus preventing the passageto the drain or waste pipe of any solid particles liable to clog thesame. It will beevident that upon unlocking and removing the door thebasket with its contents will be withdrawn therewith, allowing suchcontents to be readily removed and the interior of the trap to becleansed of all adhering deposits in a rapid. and thorough manner.

I may provide for use within the basket 22 a strainer sack 24 composedof fine gauze material of any suitable sort secured at its mouth to asupporting and sustaining ring 25. This strainer sack is designed to fitWithin the basket 22 and to be supported from the mouth thereof. Thepurpose of this sack is to catch and retain any grease which mightpossibly discharge through the meshes of the basket, thus enabling thegrease to be caught and saved for any desired use and also preventingpassage of the same to the waste pipe and the objections resultingtherefrom.

It will be seen from the foregoing description that my inventionprovides a trap for use with kitchen sinks which is not only simple ofconstruction and capable of being applied for use at a low cost, butwhich will efi'ectually prevent clogging of the waste pipe and theescape of gases or odors, while at the same timeadmitting of the removalof the trappedparticles and thorough cleansing of the trap, wheneverdesired, in a thorough and convenient manner. Other advantages incidentto the invention will be readily understood from the foregoingdescription.

Having thus fully described my invention, I claim 1. A trap for use withkitchen sinks comprising a casing having an inlet at its top and anoutlet at its bottom, a removable cover closing the open front of saidcasing, means for securing said cover in position, and a bag carried bythe cover and removable therewith.

2.v A trap for use with kitchen sinks comprising a casing having aninlet at its top and an outlet at its bottom, a removable cover closingthe open front ofsaid casing, means for securing said cover in position,a supporting rin carried by the cover, and a bag carried %y the ring anddepending therefrom and removable with the cover.

In testimony whereof I aifix mv signature.

OCTAVE J. ST. PIERRE.
